Get rid of the "illegal symbol" restriction

I just spent 10 minutes trying to make a post in the bug report section. You know, where you're supposed to post links of evidence and things. Too bad links to websites tend to use "illegal symbols" which prevent you from submitting posts here. Then to make it worse, it doesn't even show you which symbol that you used is illegal. So you end up removing a line here or there, pressing submit, trying to see if it will actually be accepted - butchering the post you just made.

"(" or ")" -parenthesis- aren't weird symbols, but somehow they are not allowed. I don't think we are trying to use "arabian" symbols or stuff like ♪ } ‗♠ ▓ ¯, just basic punctuation. Maybe the "" are not allowed too, I don't see the reason.
